How the Global War on Terror Inadvertently Strengthened Iran's Regional Position

Before 2001, Iran operated under a form of strategic containment. To its east, the Taliban regime in Afghanistan was ideologically hostile to Shia Islam and had massacred Iranian diplomats in 1998. To its west, Saddam Hussein's Iraq had fought a devastating eight-year war against Iran and remained a Sunni Arab counterweight to Iranian influence. Iran was also excluded from the Gulf Cooperation Council (GCC), the six-member bloc of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE, which was itself partly conceived as a collective response to the Iranian Revolution of 1979. This dual encirclement kept Iran's regional ambitions in check.

The post-2001 landscape changed this calculus fundamentally. The US-led invasions removed both hostile regimes. In Afghanistan, the Taliban fell and a new government took shape in Kabul and key northern cities such as Mazar-i-Sharif, where Iran had maintained ties with non-Pashtun communities. In Iraq, cities such as Kirkuk and Mosul, both located in Iraq, not Yemen or Palestine as sometimes misidentified, became flashpoints of the sectarian conflict that followed the fall of Baghdad. Aleppo in Syria later became a central battleground in the civil war that Iran would enter to defend the Assad government. These geographic theatres were not incidental: they formed the physical corridors of what Iran would build into its regional influence network.

India's own strategic calculus in this region is shaped by energy dependence, diaspora interests, and connectivity. The Chabahar Port in Iran, developed with Indian investment, is specifically designed to give India overland access to Afghanistan and Central Asia without transiting Pakistan, a direct response to the region's shifting power geometry.
